HOWTO: Set up vim-latex

1) Create configuration file ~/.vim/ftplugin/tex.vim:

    " set viewer rules
    let g:Tex_ViewRule_dvi = 'okular'
    let g:Tex_ViewRule_ps  = 'okular'
    let g:Tex_ViewRule_pdf = 'okular'

    " set compile rules
    let g:Tex_CompileRule_dvi = 'latex -src-specials -interaction=nonstopmode $*'
    let g:Tex_CompileRule_ps  = 'ps2pdf $*'
    let g:Tex_CompileRule_pdf = 'pdflatex -interaction=nonstopmode $*'

    " set default target format
    let g:Tex_DefaultTargetFormat = 'dvi'

    " disable use of makefile
    let g:Tex_UseMakefile = 0

    " set intendation for LaTeX files
    set sw=2

    " use <C-n> to automatically cycle through all the labels
    set iskeyword+=:

2) Add to ~/.vimrc:

    " make vim to invoke LaTeX-Suite when opening a TeX file
    filetype plugin on

    " set grep to always generate a file name
    set grepprg=grep\ -nH\ $*

    " enable automatic indentation as you type
    filetype indent on

    " load vim-latex for empty TeX files
    let g:tex_flavor='latex'
